Character Manipulation Function
int __iscsymf(int c);
int iscsymf(int c);
Internationalization (I18n) Function Overview
The __iscsymf/iscsymf functions return a non-zero value if c is a letter or an underscore. The integer must be in the ASCII range, 0 - 127.
I18n Issues
These functions operate only on ASCII characters; they cannot be used for multibyte or wide-characters, or single-byte characters outside the ASCII range.
In addition, there are no wide, multibyte, or generic versions of __iscsymf/iscsymf.
If possible, use an alternate function such as one of the isalpha functions, which will test for a letter, though not an underscore.
__iscsymf/iscsymf depend on the LC_CTYPE category setting of the current locale.
